Further to my previous thread re: VFD suppliers, I have ordered a Hitachi WJ200 - should be here in the next few days.
Downloaded the manual and started studying it - wow, so many parameters to program !
Now, I'm wondering about over speeding the motor. It'll be driving a 2hp Baldor M3587T 3ph, 1740rpm motor.
I had never considered over speed as an option until I started reading the manual and VFDs in general.
I think 6 ~60 hz are the factory defaults but I think its possible to input up to 400hz as a maximum.
I'm relatively new to all of this and jumping it up to 400hz just seems like a bad idea to me but would it take 120 hz to effectively double the speed of the motor to ~3400 ? I mean, would the motor take it ? Depends, I suppose on the load and whether or not it would over heat ?
TIA
